METAL SLIDE ASSEMBLY FOR TABLES Filed Sept. 1, 1950 s Sheets-Sheet s3iwentor Patented Mar. 17, 1953 rrso smrs QFFECE- The present inventionrelates to table slides such as are ordinarily included in extensibletables of various types.

At the present time there are three general types of extensible tables.One of these is the sc-called split leaf type in which the leaf which isto be inserted when the tableis extended is of a two-part,hingedly-connected structure that is mounted on rods in the slide. Thesecond is the so-called straight leaf type, in which the leaf to beadded is one single straight piece that is normally supported by theslide beneath the table top when not in use. The third is the so-calledfour leg type, in which the slide assemblies at each side are simplyconnected together to form a one-piece slide construction.

Each of the several types of extensible table above mentioned includes aslide assembly at each side of the table to provide the sliding movementwhich is necessary for extending and collapsing the table. Obviously, onhalf of the table top is connected to an element of the slide assemblyat each side thereof and the other half of the table top is connected tothe complemental elements of the slide assembly.

The present invention has in view as its foremost objective theprovision of a table slide which includes a pair of slide assemblies ofdistinctly novel construction and which presents certain decidedadvantages. ihis slide assembly may be generally characterized asincluding certain metallic parts which, when assembled, Provide achannel which slidably receives one angle of an angle bar that isconnected to one of the table top parts. Provision is made formaintaining the Sides o the a n in ccu t l s ced re a n and for limitingthe sliding movement of the angle that is assembled therein.

More in detail, the invention has as an object the provision, in a tableslide, of a slide assembly which consists essentially of a Z member, apair of angles, and a channel member having outwardly extending flangeswith the 2 member and hannel mb a mb d to Pro d the ch nel whichreceives the angle members.

Each of the angle members is formed with a pair of elongated slots whichreceive studs that extend between the Z channel members and which are.ot w l ed i posi ion.- These st function as spac s a d as abutment meansmiting sliding movement of the angles,

Various ther mo e de aile cts a d ad an a es of the inven ion 0.11 ar sen @01 nectlQn with ca in ou e above noted. ideas in a practicalembodiment, will in part become;

apparent and in part be hereinafter stated as the description of theinvention proceeds.

The invention therefore comprises a one-piece table slide including aslide assembly which consists essentially of a '2 member, a pair ofangles, and a channel member having outwardly extending flanges with the2 member and channel member assembled to provide the channel whichreceives the angle members.

For a full and more complete understanding of the invention, referencemay be had to the following description and accompanying drawings,wherein:

Figure 9 is a bottom plan view taken about on the plane represented bythe line 9-9 of Figure 8 showing the connection of one of the anglecrosspieces to the slide assembly at one end thereof.

It is believed that the present invention is best described by firstreferring to Figure 5, which illustrates one of the slide assemblieswhich is resent in each form of table slide. The slide assembly shown inFigure 5 is referred to in its entirety by the reference character A.This slide assembly A comprises a 2 member which includes a verticallydisposed main body portion Hi; a upper o tw rdly ex ending flange H, and

a a l w rinwar ly ext nding fiance I2.

portion l9, substantially midway thereof, is a metallic strip l3 whichis adapted to function both as a spacer, as will be later described, andalso as an abutment member, limiting inward sliding movement of theangles to be later described.

At this point it is well to note that the Z member II3-Ii--I2 is madefrom an appropriate sheet metal which is readily adapted to beingstamped into the formation illustrated.

Also extending inwardly from the inner face of the main body portion II]are four studs, I4, two being located on one side of the strip I3 andtwo on the other side.

A pair of angles are designated I5 and I5. These angles are substantialduplicates and only one of them is here described in detail as that issufficient to satisfy the purposes of this specification. Thus, each ofthe angles I5 and I S has a top horizontal flange I! that is providedwith a plurality of openings I8 which are employed in securing a part ofa table top to that respective angle. Each of the angles I5 and [6 alsoincludes a vertical flange I9 that is formed with a pair of elongatedslots 20. This flange I9 engages the inner face of the main body portionIn of the 2 member with the studs I4 being received in and extendingthrough the slots 20.

A channel member comprises a vertically extending main body portion 2|and upper and lower flanges 22 and 23 which extend inwardly (speakingwith reference to a complete slide assembly). This channel member isintended to be assembled on the 2 member so as to maintain the angles I5and [6 in position between the main body portion I 0 of the Z member andthe main body portion 2| of the channel member. To this end the exposedface of the main body portion 2| is provided with a plurality ofmarkings or scorings 24 which correspond in location to the studs I4 andthe strip I3. After the channel member has been positioned so that themain body portion 2I engages the free ends of the studs I4 and theexposed face of the strip I3, it is spot welded to these elements at thepoints indicated at 24, thus providing a permanently assembled slideassembly. When so assembled, the flange 23 of the channel member engagesthe flange I2 of the 2 member and these two flanges are also securedtogether by being spot welded at appropriate intervals, such asindicated at 25 in Figure 1.

Referring now more particularly to Figures 1 to 4 inclusive, a one-piecetable slide that is intended for use with a table of the split leaf ty ewill now be described. This table slide, which is referred to in itsentirety by the reference character S, comprises a pair of slideassemblies A. Extending between these slide assemblies A are two crossbars 26 and 21. These cross bars 26 and 21 are of duplicateconstruction. Each of them is a channel bar comprising a main bodyportion 28 that is disposed horizontally, and upwardly extending flanges29 which are flared outwardly at each end, as indicated at 39, toprovide a flattened out end construction 3| that is secured to thecomposite.

flange construction I2 and 23 by spot welding, as indicated at 32.Beginning with the flattened out end portion 3I and extending inwardlyan' appreciable distance, the main body portion 28 is formed with anelongated slot 33.

Extending downwardly from the inner flange 29 of each of the crosschannels. 26 and. Z1 is a tab or ear 34, with the two tabs being formedwith aligned openings, which receive a roller rod 35. This roller rod ismaintained in assembled relation by small protuberances 36 which may bestruck from each end thereof.

Extending upwardly on the inner flange 29 of each of the cross channels26 and 21 is a tab or ear 3!. These ears 3! are formed with alignedopenings which receive a swivel bar 38. The latter is maintained inassembled relation by projections 39 which are struck from the metal ofthe bar. Intermediate its ends, the swivel bar 38 is formed with twooffset portions 40 that are flattened out and formed with openings 4|.

As shown in Figure 4, a split leaf L comprises two halves 42 and 43 thatare hingedly connected together as indicated at 44. The half 42 isconnected to the swivel bar 38 by screws 45 which pass through theopenings 4|. The half 43 rests on the roller 35 when the leaf L isfolded up in inoperative position.

A table top comprises two halves, 45 and M, which are secured to theflanges ll of the angles I5 and It by fastening members which passthrough the openings I8.

A base is shown in broken outline in Figure 3 and is referred to by thereference character B. This base is of the Duncan Phyfe type andincludes the legs 48, the upper ends of which are secured to-the crosschannels 26 and 2! by an ap propriate fastening means, such as boltswhich pass through the slots 33. Obviously these slots 33 accommodatevariations in the size of the base 13.

The operation of the split leaf table, illustrated in Figures 1 to 4inclusive, is believed to be obvious from the description of the partsgiven.

It may be briefly outlined by noting that when an increased area of thetable top is desired,- the two parts 43 and 41 are first slid apart intothe position depicted in Figure 4. This movement is accommodated becausethe angles and is will slide in the channels provided by the 2 memberIQ-I l-I2 and channel member 2I22 23, the outward sliding movement beinlimited by the studs I4 which are received in the slots 23.

The leaf L is now manipulated by swinging the half 32 about the swivel38 as a pivot. This depresses that end of the two leaves folded togetherso as to raise the opposite end. This causes the free end of leaf half43 to rise up and slide over the slide assembly at that side and as themovement is continued, the halves are opened up into the position of aleaf which fills the gap between the table top parts 46 and 41. Thelatter are now closed against the leaf L to give a finished ap pearance.

When the table is to beclosed, the exact oppo- I First modification Aone-piece table slide for a table of the straight leaf type issubstantially the same as that above described, with the changes beingdepicted in Figures 6 and 7. With such a table slide two of the slideassemblies A are employed, one being located at each side. Two crossbars 26 and 27 are also utilized. These cross bars are of channelconstruction, but the flanges 29 extend downwardly from the bases 28rather than upwardly therefrom. Moreover, the roller 35 and swivel bar38, together with the construction which is necessary for theirmounting, is eliminated. When the table is in its contracted position,the straight leaf rests on the cross bars 26 and 21 beneath the tabletop. Due to the fact that the flanges 29 extend downwardly, the cornerswhich are formed thereby are rounded. Thus the leaf may be slid overthese corners without danger of marring.

When the table is to be extended to provide increased area in the top,the two top parts which are connected to the flanges I! of the angles 15and 16 are moved apart in the manner described and the leaf removed fromits position on the crosspieces 26 and 2'! and laid across the two slideassemblies, whereupon the top parts are closed against the leaf toprovide a finished appearance.

Second modification When a one-piece table slide is to be provided for atable of the four-legged type, two of the slide assemblies A areemployed, one being located at each side of the slide. These slideassemblies are connected by two crosspieces 9 and 49. These crosspieces9 and 49 take the form of angles such as shown in Figures 8 and 9. Oneflange of each angle is secured to the composite flange 12-23 of theslide assemblies, as by spot welding, as indicated at 50, and the otherflange extends downwardly.

While preferred specific embodiments of the invention are hereinbeforeset forth, it is to be clearly understood that the invention is not tobe limited to the exact constructions, mechanisms and devicesillustrated and described because various modifications of these detailsmay be provided in putting the invention into practice within thepurview of the appended claims.
